Driving home two nights ago coming down the highway and I say to my girl.. damn, these headlights are dim. I can barely tell they're on! I notice that the dash lights are dim too but they're turned up all the way. Check the volt meter it's in the red zone. So, I guess I can scratch an alternator. I figure if I have to replace it, I should replace it with something beefy. What's a good high amperage alternator to throw in my 83 Jimmy? Thanks!
